[thelist] JS Problem - IE throwing 'null or not an object' error

[Robert Vreeland]

Have you tried explicitly setting the inline style on the li element:
li style="display:block"
I seem to recall having a similar problem a few years back that was solved 
by including the style inline to begin with.
